What Does “Apocryphal” Mean in the Bible?

It can mean

1. An example: the Protoevangelium of James, where the names of Joachim and Anne, the parents of Mary, come from.
2. Who decides: the Tradition of the apostles helped the Church recognize which books make up the Bible. That list is called the “canon.”
3. How many: the Bible has 46 books in the Old Testament and 27 in the New.
